It all started in a Berkeley, California kitchen…

In 1993, Dr. Bill Vaughan formulated the first Gu Energy Gel.

When he started out, he simply wanted to develop a more digestible fuel for his daughter, a top ultramarathoner. But what he did was create a breakthrough product that allowed athletes to effectively fuel on-the-go so they could reach their personal best. 

Innovation is what created GU Energy Labs 25 years ago. GU is still family owned and still in Berkeley, and today we offer the widest variety of the best tasting, most nutrient-rich hydration, energy, and recovery products on the market. We’ve been on a mission to optimize every aspect of diet and nutrition, which is our way of serving athletes everywhere. 

Created for daily training and competition, GU Energy Gel packs energy-dense calories in a portable packet to help sustain energy demands of any duration or activity.

The 100-calorie packet contains carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. Sodium, the primary electrolyte lost in sweat, aids in hydration by maintaining water balance. The branched-chain amino acids (leucine, valine, isoleucine) may reduce mental fatigue and decrease muscle damage.

All GU Energy Gels are vegan, gluten free, and kosher.


 

Usage
    Both GU Energy Gel and our new Roctane Ultra Endurance Energy Gel pack 100 calories into every packet. 100 calories is an ideal serving size to suck down 15 minutes before training or racing in order to top off your electrolyte and glucose stores, followed by one every 30-45 minutes along the way, washed down with a few sips of fluid.
    For optimum results, always drink at least 24-30 ounces of fluid per hour during training and racing. Exact GU intake depends on the intensity of your pursuit and your body weight and fitness level. The fitter you are and the more efficient your metabolism, the more GU you can eat each hour, up to approximately 340 calories every 60 minutes.
    Combine GU with Roctane Ultra Endurance Gel, GU Electrolyte Brew and GU Recovery Brew for the ultimate in sports hydration, fueling and recovery. Take one gel 15 minutes before training or competition and then one gel every 30-45 minutes during exercise. Drink Electrolyte Brew throughout your training or racing, and drink Recovery Brew within 30 minutes after you’ve stopped.
